The simulations of 40 Ca + 40 Ca and 93 Nb + 93 Nb collisions at E lab = 400 MeV/u have been performed within the quantum molecular dynamics approach using both the phenomenological Skyrme forces and the Brueckner G-matrix potential as the in-medium NN interaction. The ...

This convinces us that our procedure of treating the finite temperature in the mean field is correct ... time step, we need to know the matter density and the kinetic energy densities of the target and the projectile which are given as: and AT Ap pr(r,t)=pi(r,t), pp(r,t) =pi(r,t), rr(r,t =f:Mr e'0 ...

The 1982-1983 Bangladesh nutritional blindness study visited 11,618 rural households and examined 18,660 preschool-age children in an effort to determine the prevalence and determinants of eye lesions and loss of sight due to vitamin A deficiency (xerophthalmia). Risk of xerophthalmia was significantly higher for children from households without any of the indicators of relative wealth used. Almost 80% of blind children from landless households, and even a very small garden reduced considerably the chances of a household having a xerophthalmic child. Poorer households with access to less than 0.3 acres land or no garden or without a tin roof, wristwatch, radio or cycle were at least twice as likely as their more fortunate neighbours to have a young child with any type of xerophthalmia. Taking account of such socio-environmental risk factor weightings would direct the scarce resources of intervention programmes to households and children who most need them.

At optimal growth pH (3.0) Thiobacillus acidophilus maintained an internal pH of 5.6 (delta pH of 2.6 units) and a membrane potential (delta psi) of some +73 mV, corresponding to a proton motive force (delta p) of -83 mV. The internal pH remained poised at this value through external pH values of 1 to 5, so that the delta pH increased with decreasing external pH. The positive delta psi increased linearly with delta pH: above a delta pH of 0.6 units, some 60% of the increase in delta pH was compensated for by an opposing increase in delta psi. The highest magnitude of delta pH occurred at an external pH of 1.0, where the cells could not respire. Inhibiting respiration by CN- or azide in cells at optimal pH decreased delta pH by only 0.4 to 0.5 units and caused a corresponding opposite increase in delta psi. Thus, a sizable delta pH could be maintained in the complete absence of respiration. Treatment of cells with thiocyanate to abolish the delta psi resulted in a time-dependent collapse of delta pH, which was augmented by protonophores. We postulate that T. acidophilus possesses unusual resistance to ionic movements. In the presence of a large delta pH (greater than 0.6 pH units), limited diffusion of H+ into the cell is permitted, which generates a positive delta psi because of resistance to compensatory ionic movements. This delta psi, by undergoing fluctuations, regulates the further entry of H+ into the cell in accordance with the metabolic state of the organism. The effect of protonophores was anomalous: the delta p was only partially collapsed, and respiration was strongly inhibited. Possible reasons for this are discussed.

BACKGROUND: An effective embryonic–maternal interaction is crucial for successful human pregnancy. Failure of this process is a major cause of infertility and can lead to placental dysfunction resulting in recurrent miscarriage, fetal retardation and pre-eclampsia. Research is ...

We observed broad bumps at 2193 and 2359 MeV in the elastic, inelastic, and annihilation p̅ p cross sections. We find that the positions and widths of the structures are invariant to changes in the multiplicity and degree of nonperipheralism. Multiplicity distributions indicate that ...

Immigrant Muslim women have low rates of health care utilization, especially preventive care such as breast exams, mammograms, and cervical cancer screening. Religious and cultural beliefs, such as the value placed on modesty and premarital virginity, contribute to reluctance to seek health care. In addition, it has been unclear whether discussions of health care behavior that involve sexuality and reproductive health would be welcomed among immigrant Muslim women. (1) To examine the impact of religious and cultural values on health care behavior of Muslim women from immigrant backgrounds in the San Francisco Bay Area, particularly with regard to cervical cancer screening; (2) To determine whether these women would welcome discussing values and beliefs regarding sexuality and reproductive health. Our key informants were five Muslim women who identified pelvic and Pap smear screening exams as major sources of anxiety for their community, and therefore major barriers to health care. Three focus groups were then convened, including 15 women ages 18-25, to discuss these issues in more detail. Many Muslim women from immigrant backgrounds face challenges in obtaining adequate health care due to some common barriers of language, transportation, insurance, and family pressures. Additionally, many Muslim women resist screening practices that are the standard in the US but which threaten their cultural and religious values. Equally important, many health care professionals contribute to the women's challenges by making inappropriate recommendations regarding physical exams and reproductive health. The women were enthusiastic and candid in discussing these highly sensitive and taboo topics.

Abstract One of the most successful models to describe heavy ion reactions on the microscopic level is the Quantum Molecular Dynamics (QMD). At relativistic energies a covariant generalization of this model, the Relativistic Quantum Molecular Dynamics ( ...
